CephFS will follow POSIX. If a client requests an exclusive write lock than no one else will be able to get a write lock. This does not mean that other clients will automatically receive a read-only lock, it depends on the client if it will fall back to read-only or fail if it can't get a write lock. ---------------- Robert LeBlanc PGP Fingerprint 79A2 9CA4 6CC4 45DD A904 C70E E654 3BB2 FA62 B9F1 _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
